[U-Boot] [PATCH] riscv: image: save space on the magic number field
From: Chester Lin clin@suse.com
Change the symbol from "RISCV" to "RSCV" so the magic number can be 32-bit long, which is consistent with other architectures.

Sorry for sending this patch again by a personal email account because somehow I can't send an email to the mailing list by my company email. I always got rejected by a middle server.
Anyway, I have submitted a patch to the kernel mailing lists as well.
Here is a reference link: https://lkml.org/lkml/2019/9/6/80
Regards, Chester
